Nothing That Matters

Both String Theory and the Quantum Field Theories treat Time in a cavalier manner. It is taken as a given, evenly, continuosly flowing irreversibly.
Both do not explain the arrow of time. In fact the whole of Physics, except for perhaps indirectly Thermodynamic (2nd law: Entropy) can account for this arrow. String Theory does now talk of time being grainy.
But the treatment of time is inadequate in both the theories. An ideal theory should show that the theory is consistent only for forward moving time. It should show by its equations - whether time is continuous or grainy, not simply as an assumption.
Hence both theories score ZERO in this round. The score now is still (3-1)/5 in favour of String Theory.
